File System

In the Linux world, I use the dd utility to create files that need to be a certain size. Even though it works perfectly fine, its kind of annoying figuring out the output file's size of the file. This is because the size is based on the "bs" (block size) value and the total number of block size "count" together.

For example, the following dd command creates a 300 mb file called 300mb-test-fil. Each block size will be 1000 bytes, and I want of a total of 300,000 blocks.
Formula: ( (1000 x 300000) / 1000000 )
